Meaning

Adding a provider, changing version constraints, or switching platforms (lock file only has hashes for one OS) requires terraform init -upgrade or providers lock for all platforms.

Common causes

  • Provider added/changed without terraform init
  • Lock file missing hashes for the CI platform (darwin vs linux)
  • Version constraint changed
  • .terraform directory stale

⚡ Quick fix

  1. Run terraform init -upgrade and commit the lock file
  2. Add hashes for all platforms with terraform providers lock
  3. Delete .terraform/ and init again

Detailed fix by platform

Shell

  1. hcl
    terraform init -upgrade
terraform providers lock -platform=linux_amd64 -platform=darwin_arm64 -platform=windows_amd64

How to diagnose

  1. Lock — Providers listed
  2. Platforms — Hashes for CI OS?
  3. Init — Run after change?
